Description

Summary

The purpose of this study is to evaluate the safety, tolerability, efficacy, pharmacokinetics and pharmacodynamics of osivelotor.

Official Title

A Phase 2/3 Randomized, Multicenter Study of GBT021601 Administered Orally to Participants With Sickle Cell Disease and an Open-Label Pharmacokinetics Study in Pediatric Participants With Sickle Cell Disease

Details

This is a three-part, multicenter, Phase 2/3 study of orally administered osivelotor in participants with sickle cell disease (SCD).

Part A will evaluate the safety, tolerability, and efficacy of osivelotor in adult participants with SCD to determine an optimal dose.

Part B will evaluate the efficacy of osivelotor versus placebo in adult and adolescent participants with SCD for 48 weeks.

Part C will evaluate the pharmacokinetics (PK) and safety of single and multiple doses (MD) of open-label single arm osivelotor administered to pediatric participants.
